BigInteger value of

[ccie007]

I copied this code from a book on Eclipse but when I tried to run it there are red underlines under "valueOf".

Everything is fine except from these 3 terms "valueOf".I wonder if any body got a clue.This full code is below:=

import java.math.*;
import java.util.*;

public class BigInteger
{
    public static void main (String []args)
    {
        Scanner in = new Scanner(System.in);
        
        System.out.println("How many numbers do you need to draw ?");
        int k = in.nextInt();
        
        System.out.print("What is the highest number you can draw ?");
        int n = in.nextInt();
        
        BigInteger lotteryodds = BigInteger.valueOf(1);
        
        for(int i = 1; i <=k; i++)
            lotteryodds = lotteryodds
            .multiply(BigInteger.valueOf(n - i + 1))
            .divide(BigInteger.valueOf(i));
        
        System.out.println("Your odds are in 1 in "+ lotteryodds +".Good luck");
        
        
    }
    }

I fixed the problem.

I was missing this line at the top

import java.math.BigInteger;
